A gentleman bandit politely robbed a pedestrian of cash and a BlackBerry in Murray Hill, police sources said yesterday.

“Ms., give me your money and your phone,” Marco Weathers, 22, allegedly said to the 23-year-old victim after he pulled a gun on her at Madison Avenue and East 38th Street at 2:10 a.m. Monday, detectives said.

He fled with the woman’s smartphone and $88, sources said.

The victim flagged down a cop, who nabbed Weathers after a brief foot chase, said a DA spokesman.

Fortunately for him, the Secret Service detail had departed.

Two days after Michelle Obama dined at the Gramercy Tavern, a burglar slipped inside the famed eatery and swiped a purse, police sources said yesterday.

An unidentified man entered the establishment through a side trash-bay door at 42 E. 20th St. at 8 p.m. Saturday, cops said.

He took an elevator to the basement, walked into an office and grabbed the purse containing $100, credit cards and the owner’s ID, the sources said.

Two days earlier, the first lady had been a patron.
